Day 20 in the Monster-Bator and I hear 2 distinct peeps- Likely from the banties that were under a hen 1 day. Cannot see a thing in the trays. Thanks to advice here, I have placed 4 Rubbermaid plastic trays on the tile to replace the missing water tray: 3 @ 6x15 and then 1 long narrow one. This fills the entire area that the tray would fill. I have PILES of sponges in them because the humidity would only get to 40 % without them. It is running 53% at the moment.
I will say these redwoods are NOT the thing for people who want to sit and watch or hover. Time to go do something else
